Hearing aid with a battery compartment

Abstract

The invention relates to an electrical device with a battery compartment that all batteries can be accommodated therein and in the event that the battery dies, battery fluid is prevented from escaping into the interior of the electrical device. The battery compartment comprises a battery compartment casing which can be provided in or on an area of the electrical device, said battery compartment casing comprising a battery recess for accommodating a battery, with the battery being held in a predetermined position in the electrical device by a permanently magnetic area of the electrical device when the battery compartment casing is in a use position in or on the electrical device. The electrical device is in particular a hearing aid.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of German application No. 10 2006 029 815.2 filed Jun. 28, 2006, which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The invention relates to a hearing aid, such as for instance a behind-the-ear hearing device, with a battery compartment.BACKGROUND OF THE INVENTION[0003]A plurality of different, compact, battery-operated hearing devices exist, in which provision must be made for an exchangeable battery and / or rechargeable battery. For this purpose, many of these hearing devices comprise a battery compartment casing which can be manually activated by way of a hinge, said battery compartment casing being able to be snapped open and closed in order to change the battery, so that the user is able to change the battery without partially disassembling the hearing aid.[0004]Batteries or rechargeable batteries are used as the power supply in all hearing aids and, depending on the ...

AI Technical Summary

Benefits of technology

[0012]It is thus the object of the invention to equip a hearing aid with a battery compartment such that on the one hand all batteries considered for the hearing aid can be accommodated therein and that on the other hand, if the battery dies, battery fluid is prevented from escaping into the interior of the hearing aid.

[0023]In a preferred embodiment of the invention, a conventional material, which is preferably not permanently magnetic, is located on the exterior of the battery compartment casing and / or on the exterior of the hearing aid. The currently used material herewith touches the skin of the wearer, so that said user does not have to deal with allergic reactions or suchlike.

Problems solved by technology

The problem here is that the sizes of the respective available battery types vary among different battery manufacturers and, if the whole hearing aid moves, a battery inserted into the battery compartment can thus move relative to the hearing aid and can thus cause dropouts and an interruption in the power supply during operation of the hearing aid or can result in damages during transportation.

The problem here is that on the one hand the spring displacement of the lug cannot be selected large enough, as a result of the material and the dimensions of the battery compartment casing, that all batteries which are suitable for the relevant hearing aid can be clamped securely and permanently, some batteries are so small that the battery can no longer be clamped by means of the battery holder device.

On the other hand, from an aesthetic viewpoint (clamping the battery and this itself should not be visible from the outside) and manufacturing-specific conditions, the recess is arranged in the wall of the battery compartment casing such that if the battery dies, in unfavorable circumstances, battery fluid can escape into the interior of the hearing aid, thereby resulting in damages and even in a total failure of the hearing aid.

A battery holder device as an additional component increases the assembly costs and thus the price of the hearing aid.

With these embodiments, it is not possible to use a broad range of differently formed batteries in a CIC hearing device, since a spring displacement of the electrical spring contact is not sufficient to compensate for different battery sizes.
